No doubt Doug , the site of someone hanging put off those watching , but were they all potential murderers ?
As mab and others have said , it isn't a deterant in countries that have the death penalty , nor was it here when we had it . If it had been there wouldn't have been a hanging for your granddad to view !
As for marines v sas taught hand to hand combat , which one's better ? , as Harry Hill says , " there's only one way to find out ! FIGHT !!!
How is the ankle mate ?
